A trait for read-only vertex data accessor.

Provided Methods

fn transform<F>(&self, func: &mut F) -> ArrayVec<u8, 256>

where F: FnMut(VertexViewMut<'_>),

Clones the vertex and applies the given transformer closure to it and returns a stack-allocated data buffer representing the transformed vertex.

fn read_2_f32( &self, usage: VertexAttributeUsage, ) -> Result<Vector2<f32>, VertexFetchError>

Tries to read an attribute with given usage as a pair of two f32.

fn read_3_f32( &self, usage: VertexAttributeUsage, ) -> Result<Vector3<f32>, VertexFetchError>

Tries to read an attribute with given usage as a pair of three f32.

fn read_4_f32( &self, usage: VertexAttributeUsage, ) -> Result<Vector4<f32>, VertexFetchError>

Tries to read an attribute with given usage as a pair of four f32.

fn read_4_u8( &self, usage: VertexAttributeUsage, ) -> Result<Vector4<u8>, VertexFetchError>

Tries to read an attribute with given usage as a pair of four u8.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
